Abstract :
We have introduced an automated learning closed-loop control scheme for the solder paste stencil printing stage of SMT. It reduces the number of board failures due to inadequate regulation of the printing parameters. Learning is used to compensate for a lack of a priori design information by exploiting empirical information that is gained experimentally
